A store sells bottles of water for $1.50 each. During the first hour the store was open, x bottles of water were sold. During the
second hour, the store sold 3 fewer bottles of water than it sold during the first hour. During the third hour, it sold three times as
many bottles of water as it sold during the second hour. The store was paid a total of $117.00 for bottles of water sold during these
three hours. The equation shown below represents these sales.
1.5x + 1.5(x - 3) + 1.5.3(x - 3) = 117
How much money was the store paid for bottles of water sold during the second hour it was open?
(A) $15.00
(B) $22.50
(C) $27.00
(D) $67.50
Answer: 22.50$
Step-by-step explanation:
1.5x+1.5(x-3)+1.5*3(x-3)=117
1.5x+1.5x-4.5+1.5(3x-9)=117
3x-4.5+4.5x-13.5=117
7.5x-18=117
7.5x=135
x=135/7.5
x=18
hour 2
1.5(18-3)=
1.5*15= 22.5$
Answer:
The answer is $22.50
Step-by-step explanation:
An albatross is a large bird that can fly 400 kilometers in 8 hours at a constant speed. Using d for distance in kilometers and t for number of hours, an equation that represents this situation is d=50t. What are two constants of proportionality for the relationship between distance in kilometers and number of hours? 50 1/50
Answer:
50Step-by-step explanation:
Speed is represented according to the equation;
Speed = Distance/Time
Given;
Distance d = 400km
Time t = 8 hours
From the formula
s = d/t
s = 400/8
s = 50
Substitute s = 50 back into the formula;
s = d/t
50 = d/t
d = 50t
This expression means that the speed is directly proportional to t where 50 is the constant of proportionality;
Hence the constant of proportionality for the relationship between distance in kilometers and number of hours is 50
Answer: Two constants of proportionality for this situation are 50 and 1/50. The relationship between these two values are that they are both reciprocals.

One a piece of paper, graph f(x)= (0.4)^x. To determine which answer choice matches the graph you drew.
Answer: Graph B
The graph of a function f(x) = 6(0.4)× is shown in graph (B) because the domain of the function is all real numbers and the range of a function is f(x) > 0, the y-intercept of the function is (0, 6)
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = 6(0.4)×
The domain of the function is all real numbers.
The range of the function:
f(x) > 0
Plug x = 0
y = 6
Thus, the graph of a function f(x) = 6(0.4)× is shown in graph (B) because the domain of the function is all real numbers and the range of a function is f(x) > 0, the y-intercept of the function is (0, 6)

a shopkeepee bought 7 books for rs.525 and sold 4 books for rs 360 .if he/she sold the remaining books at the same rate of cost price find his/her profit or losspercent
Answer:
His profit is 105 rs
Step-by-step explanation:
if he bought 7 books for 525 RS,that means 1 book costs 75 rs
if he sold 4 books for 360 RS,that means 1 boo costs 90 RS
90×7=630.
630-525=105
The first equation of the system is multiplied by 2. By what number would you multiply the second
equation to eliminate the y variable by adding?
4x – 3y = 6
6x + 2y = 10
Answer:
we will have to multiply the second equation by 3 to eliminate the y variable by adding.
Step-by-step explanation:
Given the equations
4x – 3y = 6 → (1)
6x + 2y = 10 → (2)
As the first equation is multiplied by 2,
2(4x – 3y) = (2)6
8x - 6y = 12 → (3)
As we have to eliminate y,
so multiply the second equation by 3,
6x + 2y = 10
3(6x + 2y) = 3(10)
18x + 6y = 30 → (4)
So now adding the new equations (3) and (4) will eliminate the y variable by adding
8x - 6y = 12
18x + 6y = 30
--------------------
26x + 0y = 42
26x = 42
x = 42/26
x = 21/13
Therefore, we will have to multiply the second equation by 3 to eliminate the y variable by adding.
I NEED THE VALUE OF X
Answer:
x=18
Step-by-step explanation:
Since the angle is 90, noted by the right angle symbol, we can say that 5x=90
Now we simplify each side.

Word Study Directions: Read the question. Then choose the best answer. Which word contains an open first syllable? A. connect B. frozen C. problem D. traffic
Answer:
B. frozen
Step-by-step explanation:
An open first syllable is one that has a vowel at its end and that vowel causes a long vowel sound at its end. Long vowel sounds are those sounds whose pronunciation is the same as those of the letters.
Among the words listed, fro-zen has a long vowel sound in the form of the o at the end of the first syllable. Thus it can be classified as having an open first syllable.

Abigail's family is buying a small refrigerator for their game room in the shape of a right rectangular prism. The inside measurements are 18 in., 14 in., and 24 in.
Answer:
Volume = 6048 [tex]in^{3}[/tex]
Step-by-step explanation:
Volume is the capacity of substance that a given measuring object can contain. It can be determined as;
Volume = length x width x height
In the given question, the refrigerator has an internal dimensions 18 inches, 14 inches and 24 inches.
The volume of the refrigerator can be determined as;
Volume = 24 x 14 x 18
= 6048
Volume = 6048 [tex]in^{3}[/tex]
Thus, the internal volume of the refrigerator is 6048 cubic inches.

Caroline is 12 years older than Nick. Mark is 4 years younger than Nick. If the total of their ages is 44, how old is the youngest of them?
Answer:
Hi there,
Make Nick's age = x
Caroline's age = x + 12
Mark's age = x - 4
x + (x + 12) + (x - 4)
Remove brackets
x + x + 12 + x - 4 = 44
Collect like terms
3x = 44 - 12 + 4
3x = 36
x = 12
Mark is 8 yrs old
Nick is 12 yrs old
Caroline is 24 yrs old
Youngest is Mark = 8 years old.
Hope this helps :-)
Answer:
Hi there, Youngest is Mark = 8 years old.
Step-by-step explanation:
Make Nick's age = x
Caroline's age = x + 12
Mark's age = x - 4
x + (x + 12) + (x - 4)
Remove brackets
x + x + 12 + x - 4 = 44
Collect like terms
3x = 44 - 12 + 4
3x = 36
x = 12
Mark is 8 yrs old
Nick is 12 yrs old
Caroline is 24 yrs old
Youngest is Mark = 8 years old.

A bug was sitting on the tip of the propeller blade 4 ft. Long when the propeller started to rotate. The bug held on for 3 rotations before flying away. How far did the bug travel before it flew away?
Answer:
75.39 ft
Step-by-step explanation:
r = Radius of the circle drawn by the propeller = 4 ft
Circumference of the circle is
[tex]C=2\pi r\\\Rightarrow C=2\pi 4\\\Rightarrow C=25.13\ \text{ft}[/tex]
So in one rotation the distance traveled by an ant sitting on the blade tip is 25.13 ft.
Now the ant held on for 3 rotations so distance traveled is
[tex]3\times 25.13=75.39\ \text{ft}[/tex]
The bug traveled 75.39 ft.

The front profile of a shed is depicted in the drawing, with the given dimensions. Find the area of this profile of the shed in square feet.
Answer:
135 ft²
Step-by-step explanation:
The profile is composed of a triangle and a rectangle.
Area of profile = (area of triangle) + (area of rectangle)
= (½×base×height) + (length × width)
Where,
base of triangle = 15 ft
height of triangle = 11 - 7 = 4 ft
length of rectangle = 15 ft
width of rectangle = 7 ft
Plug in the values
Area of profile = = (½×15×4) + (15×7)
= 30 + 105
Area of profile = 135 ft²
